Is this egg fertile?

[GoofyDuckLady]

My duck laid this egg 3 or so days ago, but she isn't sitting on it. It feels warm during the day from the sun, but it gets cold at night. Should I leave it there, or throw it away?

No way to tell whether it's fertile without incubating it for several days or cracking it open.

What breed is she? If you really want to hatch it, it might be best that you do it on your own with an incubator.

Ducks wait till they get a full nest before they start sitting on them. I'd leave it where she laid it .If u keep robbing her nest she will relocate. If u don't want babies then by all means rob away!

3 days is too early to tell by candling. Wait until day 7-8 to know for sure

To clarify, that would be 7 to 8 days of incubating. Not 7 to 8 days of it just sitting out like it has been

Correct. It needs to be at 99-100 degrees in order for the embryo to start growing.
